Double spring on starter plunger?

Hi,
Ive recently acquired a 1996 3.4 Tacoma and it was having the intermittent starting issue which I solved by installing the solenoid rebuild kit (thanks to info here). So it starts fine but I later found a spring which Im sure fell off the old plunger. When I reinstalled the new one, there was a spring in the clutch assembly, and so I put it all back together and the starter works fine. So whats the deal? Did a previous owner double up the spring or where there two on some starters?
Its the stock Denso. The manual shows only one. Insights?
Thanks, Art

 

It is a Toyota no telling what you might find>

I have never seen 2

Could the spring have been broken ??

Came out in 2 pieces /

as I doubt two Springs would even fit

do you still have the extra spring ?

 

Yes I have the spring and it appears to not be broken. Im usually not this sloppy with repairs but late night and next day finishing...
Im going to pull it in the morning and find out whats up. I know the plunger has a return tension so maybe the clutch is spring loaded and
that is returning the plunger - not the proper spring. Ill know tomorrow. Thanks.
